Maybe my use here of "wishes" caused some confusion.  All I meant was the preferences the voter had and wished to express, i.e. that
the voter may not mark preferences for all the candidates.  Indeed, a voter should never mark preferences he or she does not have.

Suppose there are six candidates (A - F) and the voter marks preferences for only three of them (A, B and C).  That voter has given
a clear vote in all the pair wise comparisons involving A, B or C.  But that voter has given no vote that could be used in the pair
wise comparisons involving only D, E and F.  That voter has opted out if the choice has to be made between D and E, or between D and
F, or between E and F.  That what I meant by "one vote to be used in as many pair-wise comparisons as the voter wishes to
participate in".
